Surface tension has high industrial importance in chemical. Relationship between surface tension and intermolecular forces. B. . The values decrease steadily as butanol is added to each solution, but they remain above the pure butanol surface tension of 25 dyn cm-1. 4 answers I would think 4 would have the highest surface tension because you have three OH groups and that will provide more opportunities for hydrogen bond formation. Although they have similar molecular masses (73 and 72 u, respectively), the boiling point of 1-butanamine is much higher (78 degrees Celsius) than that of pentane (36 degrees Celsius). Surface tension is the tendency of liquids to maximize their surface area. Butanol has stronger intermolecular forces than pentane because it has the ability to form hydrogen bonds, which would contribute to a higher viscosity.

Next, particle models of two alkanes (pentane and hexane) and an alcohol (pentanol) are introduced (see figure 4). Dipole-dipole forces are not as strong as hydrogen bonds, so dimethyl ether has a lower boiling point than methanol does. The experimental setupwithin their interactive videos is pretty straightforward. Identify which property liquids do not have in common with solids. OGU1NTFjYWJjMWYxODUyM2E4ZWIzN2VhOTVlNmU5YmI2NzU1ZTk0MzI5Yzk0 Surface tension results from the higher potential energy of surface molecules compared to interior molecules in a liquid. Matter and its Interactionshelp students formulate an answer to the question, How can one explain the structure, properties, and interactions of matter? The PS1 Disciplinary Core Idea from the NRC Framework is broken down into three subideas: the structure and properties of matter, chemical reactions, and nuclear processes. After discussing how hydrogen bonds are stronger than the dipole-dipole interactions between the -OH groups of alcohols, students are asked to make and eventually test one last prediction by ranking the surface tension of water, decane, and octanol. 2-Methyl-2-propanol is supplied both as a product of at least 99.8 wt% purity and as an azeotropic mixture with 11 to 12 wt% water.
